When I first saw pico the robot on the MAKE blog, I thought its Li-Poly battery, which appears gigantic here, looked familiar. It’s the same brand, Full River, and type as is used in the FlyTech Dragonfly. The builder of pico even credits the indoor R/C flyer market with developing the miniaturized batteries, thinner PCBs, and other weight-conscious components that made his dime-sized bot possible. The name pico refers to a Sumobot category which has been proposed but has so far remained unrealized, until now — although some work will have to be done to stop pico from driving off the table, as it does now. The builder is looking to an even smaller battery and motor to allow him to add other parts, such as a wireless bootloader for hands-free programming.
